Stock, par value $.001 per share, of Nellcor Puritan Bennett Incorporated, a 
Delaware corporation (the "Company"), including the associated rights to 
purchase Series A Junior Participating Preferred Stock (the "Rights" and, 
together with such shares of Common Stock, the "Shares") at a purchase price of 
$28.50 per Share, net to the seller in cash, upon the terms and conditions set
